The naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective α-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid receptor agonists, 1α,25-dihydroxyvitamin D3 analogue, and phoslactomycin B.
D(+)-Malic acid is a naturally occurring organic acid primarily produced via enzymatic fermentation of maleic anhydride or direct extraction from fruit sources. Its molecular formula is C4H6O5 with CAS No. 133-78-2. This high-purity white crystalline powder serves as a key chiral building block in industrial synthesis.
Store in cool, dry places away from moisture to prevent caking. Avoid inhalation of dust; wear appropriate PPE including gloves and eye protection. Not recommended for intravenous use without specific medical formulation approval.
